Storage system

Abstract

A storage system includes a storage grid structure and multiple remotely operated storage bin handling vehicles. The storage grid structure includes vertical storage column profiles defining multiple storage columns in which storage bins can be stored one on top of another in vertical stacks. Each of the storage column profiles have an upper end and a lower end and the storage column profiles are interconnected at their upper ends by rails forming a horizontal rail grid upon which the bin handling vehicles may move in two perpendicular directions. The storage grid structure features grid supports include multiple base angle brackets. Each base angle bracket includes a vertical flange and a horizontal flange. The vertical flange is connected to a storage column profile. The horizontal flange is connected by bolts to a floor upon which the storage grid is arranged and a web interconnecting the flanges. Each of the flanges has a first end and a second end. The first end is arranged closer than the second end to the lower end of the storage column profile to which the vertical flange is connected. The web has a recess arranged between the first ends of the flanges.

Description

TECHNICAL FIELD[0001]The present invention relates to the field of automated storage systems and more specifically to an earthquake resistant storage system.BACKGROUND[0002]The Applicant's already known AutoStore system is an automated storage system comprising a three-dimensional storage grid structure wherein storage bins / containers are stacked on top of each other to a certain height. Such a prior art system is shown in FIG. 1.[0003]The storage system is disclosed in detail in for instance NO317366, WO 2014 / 090684 A1 and WO 2015 / 193278 A1.[0004]The storage system 10 comprises a grid structure 20, see FIG. 2, constructed of aluminium profiles / uprights 1 interconnected by top rails 5. The profiles define multiple storage columns 2, in which the storage bins 30 may be stacked vertically one on top of another.[0005]A cross-sectional view of a prior art profile 1 is shown in FIG. 3 and a cross-sectional view of a storage column 2 for accommodating a stack of storage bins 30 is shown i...

AI Technical Summary

Benefits of technology

The present invention provides a storage system comprising a storage grid structure and multiple remotely operated storage bin handling vehicles. The storage system features a recessed web design that allows for the connection of base angle brackets without interfering with a storage bin. The storage system also includes multiple rail angle brackets and support struts for added stability. The technical effects of the invention include improved stability, flexibility, and efficiency of the storage system.

Problems solved by technology

The requirement of having an auxiliary grid supporting structure is disadvantageous for a number of reasons.

The supporting structure occupies space / area which could otherwise be utilized by the storage grid, i.e. it prevents optimum use of available space / area for storage; the need of a supporting structure may limit the available options for positioning of the storage system, i.e. the supporting structure may prevent the optimum positioning of the storage system since the auxiliary grid supporting structure often requires connection to a surrounding structure, such as the inner walls of a building; and the requirement of a supporting structure is not cost efficient.

Further, and perhaps more important in certain geographic areas, in case of exposure to high lateral loads due to e.g. an earthquake, the walls of a building supporting a grid structure may be exposed to additional unforeseen and detrimental loads.
